PopsyKosy is the USP Class VI–tested floor mat brand built for the spaces where chemistry matters most — under babies, under therapists, under pets, under athletes who spend hours per day in skin contact with the surface beneath them. Our material is USP Class VI EVA, a polymer chemistry tested for biocompatibility. Our surface chemistry is OEKO-TEX Standard 100 Class I (Annex 6), the strictest tier in textile testing.

Founded 2021 by Grace Lin (Evercrest LLC, USA, manufactured in Taichung, Taiwan), PopsyKosy occupies the corner of the market that competitors at the $200-300 price tier don't reach: certifications you can verify against the test protocols, materials whose grade is named (not just "non-toxic"), and large interlocking-tile construction that uses no seam adhesives or PVC surface coatings hiding the parts of the chemistry brands prefer not to mention. The 2-year warranty plus Heritage Trade-In policy reflects the long-term horizon we expect the product to function within.

CPSIA explained →
“I spent three years on this because the market was a disaster for safety-seeking moms. Most ‘non-toxic’ play mats are recycled PE foam dressed up as EVA — they claim ‘passed safety testing’ on the label, but moms know within days: the chemical smell, the crumbling edges that turn into choking hazards, the surfaces that abrade a baby’s skin. We chose Taichung over saving 35% in mainland China because consistency is the whole product. Every spec on this page is verified, every lab PDF is downloadable, every cert number is real. USP Class VI biocompatibility isn’t a claim we make lightly.”

pH 6.5–7.0 Medical-Grade Trampoline Mat: The Only EVA Rebounder Engineered for Skin-Safe Wellness

The surface your family bounces on matters. Most trampoline mats are manufactured from recycled polyethylene—a material that registers pH 9.5–10, deeply alkaline and incompatible with healthy skin. PopsyKosy's pH 6.5–7.0 Measured Rebounder Mat is engineered from 100% pure virgin USP Class VI–tested EVA, matching the acid mantle of baby skin and infant wellness standards. This is the only trampoline mat in the world certified OEKO-TEX Class I, the highest environmental and human safety designation.

Why pH Balance Matters for Your Family's Rebound Practice

Your skin maintains a naturally acidic pH of 4.5–5.5. This acid mantle protects against pathogens, moisture loss, and microbial colonization. When surfaces breach this pH window—particularly alkaline PE mats at 9.5–10—they disrupt skin microbiota and can trigger irritation, especially in children under five.

PopsyKosy's measured pH 6.5–7.0 EVA formulation respects this biological fact. Our mat won't strip or irritate. Parents report softer skin, fewer rashes during active play, and noticeable comfort differences within the first week of use. The material is also 99.99%+ antimicrobial on its TPU anti-scratch surface layer, verified under ISO 21702 and carrying USFDA registration #3010700940.

Our 5-layer architecture—TPU anti-scratch coating, EVA print film, air chamber, high-density EVA core, and EVA grip base—distributes impact while maintaining structural integrity across 500,000+ household uses. The mat arrives in two thickness options: the classic 0.5" (12mm) Signature for everyday rebound practice, or the 1" (25mm) Boulder Ultra-Thick for high-impact training and therapeutic applications.

Engineered for Longevity: Materials, Testing, and Certification

Medical-grade EVA is significantly more expensive than recycled PE. We chose it because it resists oxidative breakdown, maintains dimensional stability, and doesn't off-gas harmful volatiles. Every PopsyKosy mat undergoes rigorous third-party testing:

  • CPSIA & ASTM F963: Consumer safety and toy durability standards
  • ASTM F1292 (2-meter drop): Impact attenuation for play surfaces
  • Prop 65 & USP Class VI: Zero carcinogenic compounds or plastic leachates
  • EN71: European chemical safety for children's products
  • OEKO-TEX Class I: The world's strictest certification for skin contact textiles

Manufactured in Taiwan with 2,847 verified parent reviews and a 4.95-star rating, our mats carry a 30-day satisfaction guarantee, 2-year structural warranty, and lifetime antimicrobial protection. The TPU surface remains active against viruses and bacteria for the life of the product—no reapplication required.

Wellness Rebounds: Science-Backed Benefits for Movement Practice

Rebounding is one of the few full-body movement practices that activates lymphatic circulation, strengthens stabilizer muscles, and improves proprioceptive awareness simultaneously. A quality mat is foundational. The pH 6.5–7.0 formulation ensures your skin barrier remains intact during frequent use, which is especially critical for:

  • Young children: Developing skin microbiota benefit from non-alkaline contact surfaces
  • Athletes in training: Repeated micro-impact without epidermal disruption accelerates recovery
  • Therapeutic practitioners: Dermatologically safe for sensitive, compromised, or post-treatment skin
  • Multi-generational households: One surface safe for infants through grandparents

The Signature 0.5" mat suits indoor living spaces, daily wellness routines, and families prioritizing portability. The Boulder Ultra-Thick 1" option serves athletes, clinical settings, and households where maximum impact absorption is non-negotiable. Both are available in four colorways—Desert Sand, Glacier Grey, Baby Coral, and Totem Beige—each designed to complement modern wellness spaces.

For the 0.5" Signature, the current pricing reflects 15% off standard retail: starting at $109 for single units, scaling to $169, $279, and $339 for bulk household or studio deployments. Explore the full range in our Everyday Collection and Ultra-Thick Collection.

Frequently Asked Questions

How does pH 6.5–7.0 EVA differ from standard polyethylene trampoline mats?
Standard PE mats register pH 9.5–10, which is strongly alkaline. This pH disrupts your skin's natural acid mantle, potentially causing irritation, especially with frequent contact. PopsyKosy's pH 6.5–7.0 measured EVA is formulated to match infant and child skin biology. It's gentler, antimicrobially active without additives, and certified OEKO-TEX Class I—a standard PE mats cannot achieve.

Is the antimicrobial protection permanent?
Yes. The antimicrobial property is inherent to the TPU surface layer, not a coating or finish. It remains effective for the life of the mat, tested and verified under ISO 21702 and
